Method and device for preparing carbon material by heating molten salt and pyrolyzing biomass through solar energy

The invention provides a method and a device for preparing a carbon material by heating molten salt and pyrolyzing biomass through solar energy, relates to the technical field of preparing the carbon material through the biomass, and aims to solve the problems that the technology for preparing the carbon through the molten salt cannot continuously prepare the carbon, the energy consumption is relatively high, and the mass production is difficult to realize. And the carbon production quality is ensured, the carbon production time is shortened, and the carbon production efficiency is improved. In the pretreatment of the biomass, high-temperature hot gas obtained in the pyrolysis reaction is used for ensuring a drying system, so that waste gas resources are fully utilized, and meanwhile, the pipeline safety and the pyrolysis efficiency are also ensured. In the separation operation, a plurality of layers of filter screens and a push plate are utilized to separate the reacted fused salt from the prepared biomass c
